  • Publication number: 20150377077
    Abstract: A Rankine cycle for recovering waste heat from an engine includes a Rankine cycle circuit having a pump, a heat exchanger, an expansion device, a cooling device and a bypass circuit. The bypass circuit selectively provides a flow path for working fluid to bypass the expansion device, and includes a flow control valve actuated by a working fluid pressure differential to selectively open or close the bypass flow path. The expansion device includes a drive member directly coupled to a front end accessory drive (FEAD) of the engine such that a rotational speed of the expansion device is dictated by engine speed and the expansion device is free from separate speed control. The expansion device provides torque to the FEAD via the drive member when the system is in a waste heat recovery mode thereby reducing engine load and improving fuel economy.

  • Publication number: 20130199173
    Abstract: A Rankine cycle system and method is described and illustrated, and in some embodiments includes an expander, a pump, a condenser, and a receiver comprising a variable fluid volume at least partially defined by a movable member, wherein the variable fluid volume defines at least a portion of the working fluid flow path between the condenser and the inlet of the pump. Also, a method of charging a Rankine cycle system with working fluid is described and illustrated, and can include applying a regulated pressure to a chamber located within a receiver, introducing the working fluid to the Rankine cycle system, the working fluid being separated from the chamber by a movable member of the receiver, monitoring displacement of the movable member, and stopping the introduction of working fluid into the Rankine cycle system when the movable member reaches a predetermined position.

  • Patent number: 8263280
    Abstract: The invention provides a solid oxide fuel cell system including a fuel cell stack having an anode side and a cathode side, an anode tailgas oxidizer for oxidizing an anode exhaust flow from the anode side to produce an oxidized anode exhaust flow, and a heat exchanger. The heat exchanger includes a first inlet for receiving a cathode exhaust flow from the cathode side of the fuel cell stack, a second inlet for receiving the oxidized anode exhaust flow, and a mixing region for combining the cathode exhaust flow and the oxidized anode exhaust flow to produce a combined exhaust flow. An air flow path for supplying air to the fuel cell stack to support an energy-producing reaction in the fuel cell stack extends through the heat exchanger so that heat is transferred from the combined exhaust flow to the air traveling along the air flow path.

  • Patent number: 7964176
    Abstract: Relates to a process and apparatus that improves the hydrogen production efficiency for small scale hydrogen production. According to one aspect, the process provides heat exchangers that are thermally integrated with the reaction steps such that heat generated by exothermic reactions, combustion and water gas shift, are arranged closely to the endothermic reaction, steam reformation, and heat sinks, cool natural gas, water and air, to minimize heat loss and maximize heat recovery. Effectively, this thermally integrated process eliminates excess piping throughout, reducing initial capital cost.

  • Patent number: 7395854
    Abstract: Systems and methods for a temperature control loop in a vehicular engine compartment to concurrently cool at least two devices with a single fluid supply source when each device requires the cooling supply fluid to have a distinct temperature. The supply fluid, having a first temperature, can be simultaneously routed through a primary heat exchanger and a mixing valve. The primary heat exchanger cools the first temperature fluid to produce a second temperature fluid. The mixing valve controllably receives at least some of the first temperature fluid and some of the second temperature fluid discharged from the primary heat exchanger and mixes the respective fluids to produce a third temperature fluid. The second temperature fluid not diverted to the mixing valve is used to cool a first device located downstream of the primary heat exchanger. The third temperature fluid is used to cool a second device located downstream of the mixing valve.
